SPECIFICATION forming pari: of Letters Patent 10,382,725 dates May 15L 188s; I Application tiled February 23, 1.898. Serial No. 264,958. (No model.)

To aZZ whom it may concern.-

Be it known 'that'L ANDREW PATERsoN, of McKeesport, Allegheny county, Pennsylvania, have invented certain new and useful Improvements in Lathe-Tools, of which the following is a specification. Y

This invention pertains to lathe-toolsto be employed, preferably, iu a turret-lathe, the tool being of that general variety known as box-tools, consisting of a block carrying several tools intended to perform simultaneously several cutting operations upon a piece. The exemplification chosen for illustration has been employed in working up the nipples of tubular Wagon-axles.

My improvements will be readily understood from thefollowing description, taken in counelctiou with the accompanying drawings, in w ich Figure lis a plan of my improved lathe-tool, v shown as operating upon the nipple of a tubular Wagonaxle; Fig. 2, anend view of thetool,

end Fig. 3 a side view ofthe front portion of the same.

In the drawings, A indicates the shank of the tool,adapted to be held in an ordinary turret; B, ablock formed on thefrontend thereof; C, an axial socket in the tool adapted to receive a bit or drill; D, a twist-drill in this socket, the office of this drill being to bore into the end of the axlenipple and produce a hole which may be tapped to receive a block to close the oil-cavity of the axle; E, a socket to one side of the central. socket and parallel therewith; F, a similar socket upon the other side of the tool, all these sockets being cylindrical and -adapted to receive the cylindrical shanks of tools; G, pinchingscrews disposed vertically alongside the several sockets and adapted to servein firmly clamping the shanks of the tools in the sockets, these screws being simple collar. screws whose collars go down into counterbores and bite upon the tool-shanks; H, a disktool provided with a shank engaging the socket E, the cutting portion of this tool inthe illustration consisting of a disk'who'se faces take the facing cut upon the end of the axle-nipple, and provided with a central conical'boss which takes' a chamfering 'cut at the point of the nipL ple; J', a disk tool whose shank is secured in ery contour adapted to producelthc desired shape at the nipple-shoulder, the extreme pe riphery of the disk forming the cutting-tool for taking thel sliding cut upon the nipple; K,

j the socket F, this disk having an ogee periph- Worm-wheels, one upon the shank of each ot'l the disk tools, these worm-wheels being slipped upon the toolshanks 'behind the disks and secured thereto by keys or feathers; L, worms, one fqr each Worm-Wheel, these yWorms being jourualed in the block verticallyalongside the worm-wheels and provided at their. .tops with .square heads, by which they may be readilyA turned by means of a wrench; M, the end portion of a wagonaxle in position to be operated upon; N, a gap or notch cut in each disk tool, so as to produce a cutting-edge thereto, which edgemay be radial or a proper tangential `de v parture from it.

The tools being properly adj usted and the axle inrotation,the tool is fed endwise to the axle. The drill bores the central hole, the disk O turns off the body of the nipple, and finally finishes vthe shoulder of the nipple, and at this time the disk K faces the end of the nipple and chamfers it.V The disk tools are adjusted tov produce the proper diameter of Work by rotating them until their innermost cutting portions occupy the proper positions, and'this adjustment is effected in a most obvious man.- ner through the medium of the worms, the pinching-screws being properly slackened, of

course, during the adjusting operation. The

disk toolsarekeptsharpbygrindingtheproper wall of the notch. This grinding away of the wall of the notch would, obviously,increase the diameter of the work produced by thecutting; but this maybe compensated for by readj-ust. ment of the tools through the vmedium of the Worms.k The disk tools may be made cheaply and in quantity and with interchangeable shanks to fit the sockets and worm-wheels. Changes in the character of workrproduced may be made by changesin the contour character of the disk tools, the same wornrwheels, however, being employed. For more complicated work more sockets may be provided in the block and more disk tools employed in an obvious mann DGI'. i Q

I have referred tothe outer sockets as being parallel with the center socket and with each other. In practice it will be highly desirable that these sockets be thrown a trie out of parallelism with the axis of the revolving axle, in order that proper clearance may be given to the faces of the cutting-disks.

I claim as my invention 1. In alathe-tool, the combination, suhstair tially as set forth, of an attaching-shank, a block upon the forward end thereof, an axial socket therein, one or more sockets parallel thereto, pinching-screws for the sockets, a bit secured in the axial'socket, and disk tools provided with shanks engaging the other sockets.

2. In a lathe-tool, the combination, substanof said outer sockets provided with a shank 25 engaging said worm-wheel and socket.
